British retailer Debenhams has launched the lightest ever T-shirt bra.

Weighing less than two ounces, the 18 pounds T-shirt bra has a moulded cup that is glued together rather than stitched.

Almost half as light as most bras, it weighs a fifth of the typical gel push-up varieties.

Trials found the lingerie gives the sensation of being naked under clothing, feeling like a 'second skin'.

“The search for a bra that fits, flatters and is comfortable is as hard as finding the right man. We’re confident once women try this, they will never wear another T-shirt bra again,” the Daily Express quoted Sharon Webb, Debenhams’ head of lingerie buying and design, as saying.
